Windows XP Logon Hangs after a while

Hello,

I have a Windows XP Pro machine that developed a problem within the past 6 months where the login will hang and not complete after the system has locked the screen. This appeared to happen after installing a remote access product from logmein.com. Basically, the program operates like the remote desktop but works through a proxy so your PC is not on the open network available for any hacker to try and login.

The computer can be up and running for days and then gets into a state where you can't login. You click on the user, enter the password, it attempts to login but the system is locked up at that point from a UI perspective.

I can however telnet in (I know, telnet is not secure) and run applications, see the processes that are running, etc. I am usually able to reboot the machine via shutdown -f -r over telnet but not always.

I am trying to figure out how to debug this without reinstalling XP as a brute force method.

Any help would be appreciated.

Thank you.

One more piece of information. I have uninstalled the logmein.com application and the problem persists. I am inclined to believe that logmein.com installed some DLL that interacts with the desktop due to the nature of the beast and that uninstalling logmein.com may have left this dll some other service behind.

One thought would be to get a registry cleaner and manually remove the erst of it. You can also try creating a new profile and copying the contents of it, see if it persists.
Something else, to check system files you can try inserting the winCD and going to
start -- run -- sfc.exe /scannow to check the system files,
Or, reset TCPIP (or reinstall TCP/IP)
reset like this
start -- run --
netsh int ip reset c:\resetlog.txt
this should reset the reg. entries for TCP/IP to the original settings. -- Note: this only works sometimes, but it should be the first step as it takes about 3 sec. to run, if it works, you should know quickly.
Or, to reinstall
regedit, find the Winsock2 key, delete it (back it up first)
reboot
then go into network properties and "install" TCP/IP (a bit tricky, look up the documentation for specifics).

And if the above doesn't work try to restore to a previous time (before instaling the malware software)
